kupid_search_courses
AI agents call kupid_search_courses to retrieve information from Ku Portal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to search or retrieve course information from the Korea University portal. This is a read-only query operation with no ability to modify, delete, or execute external actions. The blast radius of misuse is minimal—an AI agent could only retrieve course data that the authenticated student can already access. Low severity due to information retrieval only.
From the tool's definition Tool name 'kupid_search_courses' combined with server context that enables students to 'query their KUPID portal' for 'courses' suggests a retrieval operation.
